We've stayed at Spring Hill with a group of friends and our dogs over several Xmas-New Year's weeks. It's a wonderful place for a winter get-away: downhill skiing right around the corner at Stratton and Bromley, cross-country skiing and snowshoeing right out the door, as well as at several excellent cross-country skiing centers and on the catamount and other trails in the area. It's just a short hop to Manchester if you like to shop, and lots of great, small farmstands for local cheeses and other lovely items (we are HUGE fans of Taylor Farms). Lots of room for folks to spread out, and the property is very private (the house is well back from the road, with a brook between the property and the road - very nice for keeping the dogs contained!)
Great place to stay in the Summer and Fall, too.
